Beethoven recording Search

Back in 1960, I purchased an LP of Beethovens 5th Piano Concerto produced by CBS as part of their 'Masterworks" series of Vinyl LPs. ( No. BLD 7130). It was performed by Eugene Istomin with the Philodelphia Orcgestra conducted by Eugene Ormandy.

The opening bars are magnificent, but pretty much garbled by now and I would dearly like to replace it. I have always believed it to be the finest recording of this piece and nothing I have heard since matches it.

I am now in the process of converting my collection of LPs to digital after 30 years of storage and, after purchasing a decent turntable am absolutely swept away by the quality of reproduction of these vinyls. It's not surprising the vinyl LPs are making a comeback, but storage, mobility, space and convenience are the driving factors in my case. However, the vinnyl LPs are going nowhere but back into storage for future enjoyment.

Could anyone help me in finding a replacement recording of this LP. It appears on several websites, but I always receive a different recording in the post which I have to return. Personally, I think that is dodgy practice, but that's life these days.
